Title: Improvements in or relating to deflecting circuits for cathode ray tubes
IPC: H03K4/28
Filed: 1937-09-27
Abstract: 502,830. Valve circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Sept. 27, 1937, No. 26085. Convention date, Sept. 26, 1936. [Classes 40 (iii) and 40 (v)] To produce a current or voltage of non- sinusoidal waveform in a reactive or capacitative load Lo, a voltage recurring at a given frequency is impressed on the load, which exhibits resonance at the fundamental frequency and at least one harmonic. The deflecting coil Lo of a cathode-ray tube is in the output circuit of an amplifier 9 and is shunted by resonant circuits x, y, z. The input of the amplifier is connected to a generator 1 of impulses which produce a saw-tooth current in the coil. A damping circuit 17 is also shunted across the coil. One of the series resonant circuits is tuned to a frequency between the fundamental frequency and the second harmonic, a second between the second and third harmonics, and the circuits are so tuned relatively to the deflecting coil that the combined circuits exhibit parallel resonance at the fundamental frequency and its second harmonic. The periodic impulses drive the valve 9 from plate-current saturation to plate-current cut-off. The circuit is also used for applying a saw-tooth voltage to deflecting-plates through a step-up transformer, Fig. 3 (not shown). The generator 1 is described in Specification 442,334.

Abstract: 836,469. Opening, filling and closing bags. MACHINEFABRIEK VORHEEN JANSEN & SUTORIUS N.V. Aug. 21, 1957, No. 26395/57. Class 94(1). A machine for opening, filling and closing bags comprises opposed suction members 2, 15 which grip and pull apart the walls of the bag mouth, and cooperating pairs of members 11,17 at each side of the suction members, which grip the edges of the bag mouth and are moved laterally inwardly and outwardly as the suction members are moved apart and towards one another. The members 2 and 11 are slidable on a fixed frame 1 and provided with rack teeth 6 and 12 meshing with pinions 9, the member 2 being urged outwardly by a spring 7 encircling a rod 3 carrying a roller 5 engaging a rotary cam 34. The members 15 and 17 are slidable on a movable member 13 and provided with rack teeth 20 and 21 meshing with pinions 19, the members 17 being formed with slots engaging projections 35 on the members 11. The member 13 is carried by two levers 26 each formed with a slot 27 engaging a slide block 28 pivoted to the frame 1 and a downwardly-extending slot 30 engaging a pin 31 on a bell-crank lever 32 acted on by a spring 33. The members 2 and 15 are formed respectively with channels 22 and 24 connected to suction conduits 23 and 25. The levers 32 are operated by linkage (not shown) against the action of the springs 33 to move the member 13 away from the frame 1 until the blocks 28 engage the ends the slots 27 and then to swing it upwardly to the inclined position shown in Fig. 4. A collapsed bag is then inserted between the members 2 and 15, so that it is held by suction applied through the member 2, and the levers 32 and associated parts are returned to their initial positions by the action of the springs 33 so that the edges of the bag mouth are clamped between the pairs of members 11, 17. The cam 34 is then rotated to allow the member 2 to move outwardly under the action of the spring 3 and the motion of this member is transmitted by the gearing and projections 35 to the members 11, 17 and 15 so that the bag mouth is opened for the reception of a verticallymovable filling tube 36. After the bag has been filled, the cam 34 moves the member 2 inwardly, so that the members 11, 17 and 15 are returned to their original positions, and the bag mouth is sealed by co-operating electrodes 37 and 38. The members 11, 17 may be provided with suction orifices. The filling tube may be locked by a safety device if the bag has not been completely opened.
